TO ALL WHOM IT MAY CONCERN:

Be it known that l, COOK C. LAWRENCE, of Homer, in the county ofCalhoun, and State of'Michiga-u, have invented a new and usei'ulImprovement in Thin-Coupling; and I do hereby declare that the followingis afull, clear, and exact description thereof, which will enable thoseskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification. in Which-'- VFigure 1 represents my improved coupling connected with a thill andaxle.

Figure 2 is a top view of the clipplate. l

Figure 3 is'a partial top view of ythe coupling.

Similar letters of reference indicate corresponding parts.

This invention relates to an improved plan of constructing a couplingfor the thills o r poles of carriages Y und wagons, and consists inbolting together two plates on the under side of the pole or thills,provided with segments of disks on their ends, which match, when closed,to formrnerly a complete disk, in the centre of which is a hole forreceiving theend of a. plate on the bottom ofthe axle-clip. The ends ofthe plate are slotted lto receive the periphery of the disk, and theyare so connected that the thills are hveldifast while they are readilycoupled and uncoupled, as hereinafter more particularly described.

A represents an axle, on which is an ordinary clip, a, with an underplate, b, projecting forward, and curved.

u ward at the end, in which is a slot, c, fi 2 leavin a crossin, d atthe extremit that is made round to t g a g P a y in a hole in the diskB, which isformed of two parts e e', one of which parts, e, is formed onVthe end of a4 plate,

g, that lies next to the under side of the thill C, andthe other part,e', is formed on the end of a separate plate, y. The plate'g is fastenedto the thill C with bolts h h'; and the plate g is secured to theforward end of the plate g by a nut, i, on the bolt h, in such amannerlthut the end with the disk segment e' on it may beopened to standapart from the disk segment e far enough to admit the cross-pin d' onthe under plate b, in order toeifect the coupling, which is done bydrawing the plates together, and closing the segments of the disk uponthe pin d, while the disk itself enters the slot c. The plates g y aredrawn and held together by a screw-bolt, Ic, placed'- just behind thedisk'B.

This connection ofthe plates iseasily and quickly made, and the couplingis neat, cheap, andseoure. As

it wears away the screw-bolt k keeps it adjusted, so that it will notrattle or get out of order.

l Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, isf- The plates g g', provided with disksegments e e', in combination with the slotted clip-'plate 415,constructed and operatngsubstantially as herein described.
